Small Size Axis Analog Magnetic Sensors

Overview
The HMC104X and HMC105X family of magnetoresistive sensors offer a compact and highly reliable solution for low field magnetic sensing. The advantages of these patented chips include orthogonal precision two-axis sensing (HMC1052L) in a miniature surface mount package. Each of the magneto-resistive sensors are configured as a four-element Wheatstone bridge to convert magnetic fields to differential output voltages. These sensors also include patented on-die straps for offset and set/reset functions.

Our HMC104X family of very small size magnetoresistive sensors permits cost effective, high performance and space-efficient applications. The subminiature size and low-height (1.05 mm) of the HMC1041Z makes this sensor ideal for highly integrated, portable products like global positioning systems (GPS) receivers and watches.

Products in this family include:
  • HMC1041Z
  • HMC1051Z
  • HMC1051ZL
  • HMC1052L
  • HMC1053
